Product Description


Rocky Mountain’s new ETSX (Energy Transfer System) is one of the cleverest solutions to the problem of creating a suspension bike that will climb efficiently without compromising its bump-taming ability - rather like RM’s 3D-Link but with more travel.

Based on the wishbone suspension found on Formula 1 race cars, ETSX (Energy Transfer System) suspension features a unique double A-arm linkage that creates a virtual pivot point towards the front of the frame. Being extra long, it’s virtually impossible to make this swing arm react to pedal forces, yet it’s always ready to react to bumps. That’s why it really lives up to Rocky Mountain’s claim, ‘It actually helps drive you forward as you pedal over rough terrain.’
